Our ProductsO-rings

The main advantages of the elastomer / rubber O-ring are its low weight, its low space requirement, its high media and temperature resistance and its favourable price-performance ratio.  The different types of O-ring seals are static and dynamic. Static sealing is a seal in which the coupling elements are not subject to any corresponding displacement. Dynamic sealing is a seal in which the coupling elements are in corresponding movement with each other.

The O-ring dimensions and standard qualities we keep in stock meet the requirements of DIN 3771 Part 1-5, grade characteristic N. DIN 3771 Part 4 defines the permissible shape and surface deviations of O-rings.

Permissible defect sizes are differentiated according to the variety characteristics N and S. Unless otherwise specified, O-rings will be supplied according to grade N. These meet the requirements for standard quality.


Due to our own tool construction we have the possibility of a cost-effective and fast production of your O-ring dimensions with special tolerances from the desired or required material.


DIN 7716 (guidelines for storage, maintenance and cleaning of rubber products) applies to the storage of O-rings. Proper storage is important. The service life of O-rings can be affected by many influences, such as light, heat, humidity, oxygen, ozone, etc., and thus changed. The ideal temperature for storage is between +5 and +20 C. In general, storage in polyethylene bags welded together is considered optimal. We recommend not to exceed the following storage times significantly:

Generally recommended storage time of elastomers:

NBR 4 years
HNBR 4 years
FKM/FPM 10 years
VMQ10 years
EPDM 6 years
CR 4 years
